I don't know if Alonso will do WEC next year from the start before Le Mans, he will be very busy with the McLaren Renault. Maybe he could get more free time after Le Mans 2018 and get more practice at the end of the year and at the first races of 2019 season to be ready for Le Mans 2019.

I suspect his pre-LM program would be pretty light and compact (especially comparing to the 500 running-up)

0-1 day for participating the February ACO Press Conference - or he doesn't bother and just sends a video
1 day somewhere for Toyota PR duties
3-4 days for Spa 6 Hours
1 day for the ACO Rookie Simulator in Paris
2 days for LM Test weekend

Why not a third car for Le mans when Alonso and his sponsors put in part of the budget.Then it would be more affordable i'd say.Don't know the exact amount we are talking about here but it would surprise me if he'd not be able to at least raise a couple of million.

The participation of Alonso in the WEC and Le Mans will generate a lot of extra repercussion and it is reasonable that he could attract some sponsors.
Santander have decided not to renew is contract as title sponsors of Ferarri and they had come from the hand of Alonso, their colors fit with those of the Toyota Gazoo Racing and it would be great to see them on the TS050.

It makes sense for Alonso to do Spa and Le Mans only.
If Toyota fields three cars then it's no problem.
Why would he bother to race against weaker cars in 6h races?
Only to get experience in traffic maybe.

I remember some statements from Alonso from 3 or 4 months ago, he said: "I do not know what I'm going to do next year but where I'm going I will win".
It is to be expected that the McLaren Renault 2018 will be more competitive in order to reach the podium but it is difficult to suppose as a winning car.
Alonso won his world championships in 2005 and 2006 more than 10 years ago and then it is reasonable that he want to return to be champion.
The victory in the 24 hours of Le Mans and the WEC world championship could be very interesting for him.
The only coincidence between F1 and WEC is COTA and the 6 hours of Fuji, COTA is the 18th race of the season one of the last and possibly at that time of the year he has no more chances to be an F1 champion and then he could also race in Fuji in the fight for the WEC title.

But he won't be able to win the WEC title anyway if he doesn't enter 2019 Sebring, Spa, and LM, and we don't know how the F1 schedule looks yet then. LM shouldn't be clashing if the FIA respects the gentlements agreement (although we already know how that's turned out to before, look 2016) but Sebring has periodically clashed with Albert Park and Spa with Barcelona IIRC

Also I don't think he cares about the championship (he said somewhere he hasn't really even taken a look at the calendars), only winning the 24 Hours. The "other races" would just be practice and side fun

We'll see what happens. January is when Toyota say they will announce their drivers. Will he be announced then? If he isn't, does that mean he won't drive for Toyota? I think he could do the whole Super Season if he wanted. They may even fiddle with the dates to see to that, ya never know!

Agreed. At this point the championship is of no consequence for him. In future years, who knows....

TGR President Tomoyama said at TGR Festival on Dec 12, after demo driving TS050 himself, that releasing a commercial car utilizing their WEC related tech will take some time but they are releasing a concept car soon showing their vision; he said it will like a successor to LFA to show Toyota's sports car philosophy.

This Concept car is likely to be release for Tokyo Olympic in 2020.
Unlike WEC, the car will have V8 with possibly more than 4l engine.
(last I heard was 5l?)
I thought this car wouldn't have the wing/spoiler but I guess I was wrong...but I know the car will have coolest way to enter.(They don't have doors but got similar design to fighter jet cockpit)

That would set it apart from nearly every car if it's a top entry with a canopy like design. I've read around that there is a 4.0/4.4L V8 TT engine waiting to be used for cars like the LC F. I wonder if this will be coupled with 2 mgu's front and rear for a cool 1000+hp?
